Profile: Coleman Microwave Co. produces lowpass, highpass, bandpass and band reject filters. Filters can be configured as single channel, multichannel and diplexers. MC tunable diplexers consist of two tunable bandpass filters sharing a common port, which are offered in circulator designs to enhance isolation and non-circulator designs for non-directional applications, & to minimize loss. High power microwave transmitters radiate an amount of spurious output power, that is, frequency components other than the carrier frequency and the normal sideband modulation signals. We also specialize in offering machining, CAD design, drafting and aluminum dip brazing services.
